function for myself, which is the best way to go about it?

any study comparing the accuracy of brown's double exponential
model versus holt's exponential model?
Thanks in advance,

some light on the above issues.
Also if I want my final model to be a composite one involving expoential
smoothing and autro-regressive terms what is the best mode of action?
Thanks and regards,

t) in the values of parameters from
applying the above function as opposed to lapply. Why could it be so??

Hey,
I have a list of 30 odd time-series (products) in columns of a data-frame.
I want to apply time-series forecasting functions across all the columns of
the data-frame in order to determine which is the best model to use.
How do I go about this?
Phani
